OPER'AQGLASS.

SPECIFICATION forming part of Letters Patent No. 539,006, dated May 7, 1 895.

Application filed October 12, 1894. Serial No. 525,714. (No` model.)

Glasses, of which this speoication, reference being had .to the drawings accompanying and forming a part hereof, is a full and complete description, sufficient to enable those skilled in the art to ywhich it pertains to understand,

make, and use the saine.

The invention relates to opera glasses having holders attached thereto by m'eans of which the glasses can be held for use, and

focused by the hand grasping the handle of the holder; andthe object of the invention is to obtain an opera glass of more sightly appearance than has been heretofore made,

and of lighter construction; to obtain an opera glass having a holder of the kind described, the holder whereof can be easily detached from the glass by the person using the same, for placing such glass and holder in the respective cases therefor, and to obtain an opera glass having a holder of the kind named, the holder whereof, when detached, can be folded and thereby reduced in length, before being an opera glass and holder of the kind namedwherein the movable' parts or gearing shall be inclosed in such manner asl to be -protected from injury, as well as concealed from oblservation, leaving only the thumb wheel by glass obtained by us is the result of efforts to render the invention therein described of greater practical utility than it would otherwise be.

In4 the carrying out of our invention we have found it 'necessary to devise and construct mechanisms which are, by us, substituted for the mechanisms heretofore placed between the barrels ofthe opera glass for focusing the same; to devise and construct mechanisms for attaching the holder to the opera glass so that such holder can be detached from the opera glass by the person using the same; and at the same time so construct such holder and opera glass that the gearing contained therein respectively, shall intermesh or engage, and that without requiring special care or eort on the part of such person, and to devise and construct mechanisms whereby the holder can be, when de such case is not required to be noticeably larger than would be a case adapted to hold the opera glass without such holder.

In the drawings referred to, Figure l is a front or end elevation of an opera-glass and l holder embodying the invention; Fig. 2, a section through the center of the holder,with such holder removed :from the operaglass and folded-in readiness to be placed in its case; Fig. 3, a sectional viewon line 3 3 of Fig. l, viewed in the direction indicated by the arrows, with the side barrels of the opera-glass (which barrels are in no way directly affected by the invention) removed; Fig. 4, a sectional view on line 4 4 ofk Fig. 3, viewed in the direction indicated bythe arrows; Fig. 5, a bottom plan View of the parts illustrated in section in Fig. 3; Fig. 6, a section on line 6 of Fig. l, viewed in the direction indicated by the arrow; Fig. 7, a top plan View of the upper end of the holder, showing the part thereof fitting onto the parts illustrated in Fig. 5.

Fig.l3 isavertical sectional Viewy of a detachable thumb-wheel which canr be substituted for the holder when desired.

A reference letter employed toindicate a given part is used to designate such part'in all the views thereof wherever thesame appears throughout the severalffigresotl the drawings.

A is an opera glass, a a being the respective barrels thereof and a a' thebars forming part of the frame-Work of the opera glass and connecting such barrelsv together.

B is the handle of the holder.

D is a yoke connecting handle B with tube E. Yoke D consists of the part d designed to be rigidly attached to handle B; the body parts d d2 pivotally joined togetherat` one end thereof and adapted to bel opened yandA closed on the connecting pivot, and ywhen I closed forming a yoke; and the part d3 rigidly secured to the tube E, and-catch d4.- Whatwe deem the'preferable constructionof catch i d4 is illustrated in Figs. 1 and 6. lnthis construction'dis an abutment on part d' of yoke D, and d is a groove in abutment d5.

(17 is a stop on theside of abutmentd5."

d8 d8 are abutments on part d2, between which abutment d5 extendswhen the holder it in operative adjustment.

di is a thumb Wheel rotatably mounted on part d2 of the yoke and d10 is the circular` base of rotatable thumb wheeldg.

d isa notch in based.10 of thumb wheel dg, such notch corresponding with `abutment CZS, so that when the notch is over the opening or space between abutmentsecl8 d8, such abutment d5 can be extended through. the notch with groove d6 above part d2 and in place soy that rotation of the thumb Wheel will cause flange or base d10 to extend into the4 groove and so hold parts d' dzfirmly together, there` by obtaining yoke D.

F is a sleeve rigidly secured to the upper end of tube E.

fis a beveled tlangeon sleeve F.

ffare circular notches in beveled laugef. f

By reference toA Fig. -7, it will beobserved that the angefon one side oli the circular notchesf f extend radially to a greateridistance than on the othereside ofsuch`no`tche's.`

f2f2 are abutments rigidly securedto the` under side of frame'FJ of the opera glassw The frame F is secured lat the ends thereof tothe connecting-barsaa', respectively, of* the opera' glass and is by us used as a sub-` stitute for the tube heretofore used. The reinto the passage-way F2.

teatros spective abutments fj2 are in form similar to the head of a common fiat-headed screw, and in practice We prefer to employ screws to form such abutments. To attach the holder to frame F', it is merely necessary to place such holder so the abutments]c2 will extend through circular notches f'f' and then `to rotate the holder so that the beveled angef will come rigidly into place against theunder faces adjacent thereto of the abutmentsf2f2. Because of the extension hereinbefore described of the flangef on one side of the notchesf'f further, radially, than ou the other side of such notches the holder can be turned in one direction only when iu position against frame F', as described, and an eccentric or cam-shape is thereby given tosuch beveled ange whereby by the turning of' the holder, `as-described, a rigid connection between the'holder and the frame F' is made.

F2 is a passage -Way extending through frame F. F3 is a bar securedat one end thereof `to` connecting-bar C, and extending The connecting bar- C unites` the tubes `extending into the barrels a a ofthe opera glass and is the connecting bar heretofore used for such purpose.

F4 is a spr-ing Vinterposed.between bar F3 and frame `F in passage-way F2, to produce slight frictionalcontact in the longitudinal movement of the-tubes of the opera glass in barrels a a. While this spring F4 is not essential to the working of the opera glass embodying our invention, yet such spring is by us deemed advantageous in that it prevents movement of :the tubes inthe barrels a a. when the holder is being attached to the opera glass.

f3 is a geared pinion rotatably mounted in frame Ft so as lto engage or intermesh with the teeth f4f4 on bar F4.

f5 is a square hole extending through, or nearly so, the rotatable pinion f3.

H is a rotatable spindle having the squared end h at'the upper endv thereof fitting into the square hole f5 of the rotatable pinion f3 when the holder is in place against the frame F. Rotation of the spindle H will, therefore produce rotation of pinionjaud through connecting bar F3, and C, longitudinal movement of the tubes of the opera glass in the barrels a a thereof, thereby focusing the opera glass A by the rotation of the spindle II. Rotatable spindle H extends downward through the tube E and has placed thereon thumb-wheel I secured `thereto to rotate therewith.

tube. By this means any indication that the opera glass has been repaired or made over 'to embody the invention is obviated.

In the modified construction illustrated in Figs. 8 to 12, both inclusive, a different form of catch for holding the parts of the yoke in a closed position is shown, a frame-work designed to be attached to an ordinary opera glass withouttaking therefrom the adjusting devices heretofore employed for focusing the opera glass, and a different construction for securing the holder to such frame are illustrated. In this modified construction, the beveled gears secured on the sleeve or tube of the focusing mechanism of the opera glass. and the intermeshing beveled gear, whereby focusing mechanism is actuated, shown and described in Patent N o. 506,012, of October 3, 1,893, hereinbefore referred to is retained; but in this construction such driving beveled gear is rotatably mounted in frame-work J and not on the end of the spindle extending through the tube of the holder. Frame-work J consists of parts j j secured together by screws jijz. This frame-work is thereby rendered adjustable to different sizes of opera glasses. l

js is'aslot in part j through which such screws extend,

In orderv to makethe holder adapted to be .held in the right hand or in'the left, as preferred,the partsj,j, are turned up, respectively, and on the upturned ends holes fitting over the ends of the focusing tube .of the glass, or over screws extending into the ends thereof, are placed.

j4 is a hole in the upturned end of partj, and fitting over the endof the focusing tube, andy'5 is a hole in the upturned end of part j through which screw j fitting into the end of such focusing tube,fextends.

The catch here used for. holding the parts oZ d2 of the yoke D together consists simply of the spring lever K pivoted in abutment d5 so as to extend between abutments d8 d8 and engage at the hooked end k thereof with pro- Y jection Za extending between such abutments K is the spring yieldingly holding spring lever K in engagement with projection Zo.

The construction by which the holder is attached to the'` opera glass in Figs. 8 to 12 consists of lthe rotatable and longitudinally movable sleeve' L mounted ou tube E and having internal screw-threads Z adapted to engage with screw-thread-Z on projection L of frame J. H

Z2 is a flange on-tube E preventing the sleeve L from being removed or coming off of the tube E, and against which flange such sleeve is brought in close contact by-the e gagement of the screw-threads Z Z.

Mis a projection on the projection L of frame J adapted to Iitinto the corresponding hole m in the end of the tube E of the holder and thereby prevent rotation of such holder when the spindle H thereof is turned to focus the opera glass. More than one hole m may be placed in such tube E, (or in ferrule F thereon,) to enable the person using the opera glass and holder to readily attach the holder and glass together.

h is the squared or rectangular end of spindle H, and h2 is a corresponding groove or hole in the hub p of the rotatably mounted beveled gear I.

The construction illustrated in Fig. 13 consists, simply, of the non-rotatable sleeve N, attached to the frame extending between the bars d', d, as hereinbefore described, and the rotatable spindle O, having thumb wheel O at one end thereof and square (orrectangular) end O2 at the other end thereof fitting into the square (or rectangular) hole f5 of the rotatable pinion f3.

The fastening illustratcdand hereinbefore described consisting of the beveled flange F, having. openings f,f and abutments ffz, may be substituted for the sleeve L, having holes m, m, therein, shown in. Fig. 13, if preferred.
